Black Duck uncovered open source project information by analyzing its own KnowledgeBase of open source projects. The approach helped Black Duck identify cloud environments. Black Duck found Amazon to be the leading cloud environment followed, in order, by Microsoft’s Azure, Google Apps Engine and Force.com.

Article Excerpt: “When we began the analysis we expected to find projects focused on security, privacy and management,” said Peter Vescuso, Black Duck’s executive vice president, in a statement.

“The variety of projects that self-identify as ‘cloud’ is much broader in scope, reflecting the sophistication of the cloud application ecosystem and confirming the importance of OS cloud software developed to support the needs of enterprise IT,” said Vescuso.

Black Duck noted that the private and public clouds collected in its searches includes such well-known projects as Hadoop, Eucalyptus, Hyperic, deltaCloud, Open Stack and OpenECP.
